﻿June, 1S95.] Banks. Spiders of Long Island, N. Y. 77 



present a good showing. Long Island represents the northern limit of 

 quite a number of southern spiders ; such as Mahadeva verrucosa, 

 Epcira scutulata, Tlieridium glaucescens, Oxyptila monroensis, Gua- 

 phosa sericata, Auloiiia funcrea, Oxyopes sca/aris, Hyctia pikei and 

 Zygoballus sexpunctatus. Se\'eral other forms extend a little ways into 

 New England, as the genus Acrosoina, Vixia in/u/iiata, Epeirafoliata, 

 TJieridula sphcerula, Argyrodes cancellatus, Romphcea fictilium and 

 Lathrodectes mactans. It is, as far as known, the southern limit of a 

 few sub-boreal forms which extend across the northern part of the 

 country ; for example, Ergane borealis, Agra-ca ornata and Drassus 

 robustus. Being an island, it lacks some forms (perhaps not yet dis- 

 covered) which inhabit the mainland. This is most strikingly shown 

 by the fact that I have observed but two specimens of Epcira disp/icata, 

 a species widely spread and common on the mainland.
